Design and Optimization of Die Casting Process for Magnesium Alloy Radar Shell Based on Numerical Simulation

According to the material requirements and structure characteristics of the radar shell, the different die-casting process schemes were designed preliminarily. Then, the finite element analysis software Procast was used to simulate schemes. At the same time, the best process scheme was selected by analyzing simulation results. On the basis of the selected scheme, the overflow system was added, which reduced the volume content of shrinkage porosity of the casting. Secondly, the design of the orthogonal experiment was used to optimize the scheme, and the optimal process parameters were obtained. As a result, through the actual production and application, obtaining magnesium alloy die castings of shell with excellent quality.
